1 Claim.
This invention relates to a blanket and has
particular reference to a blanket suitable for use
(Cl. 5--334)
of lock stitches, as indicated at I2, are run par
allel to the edges through the plies and tape and
by the violently insane.
Ordinary blankets cannot be used in insane
5 asylums since violent inmates readily destroy
them. It is the object of the present invention
to provide a strong blanket which, though it has
the ñexibility and provides the warmth of an
ordinary blanket, cannot be readily destroyed.
lnteriorly of the tape to insure that the plies all
along the edge are in close contact With each
other, thus a?fordinga reinforced condition which O!
makes it practically impossible to start a tear
from the edge of the blanket.
Besides the above stitching, the entire surface
of the blanket is covered by crisscross lines of
10 This object is attained by so constructing the
blanket that it offers no chance for a grip which
would permit destructive tearing. It has been
found that blankets so constructed stand up for
lock stitches, as indicated at I4, which lines are 10
so run as to leave only relatively small areas
which are not tacked down by the stitches. Pref
erably the lines 0f Stitches are run at right an
periods far exceeding the periods of life of ordil5 nary blankets.
The improved construction will be apparent
frcm the following description read in conjunction with the accompanying drawing, in which:
Fig. l is a plan View showing a corner of the
20 improved blanket; and
Fig. 2 is a perspective View partly in section
and partly broken away te specifically show the
constructional details which lead to the attainment of the desired object,
The blanket comprises an intermediate ply 2
of strong fabric, such as canvas 0r equivalents,
for example, duck, etc, Prefer-amy this canvas
or duck, though strong, is of such weight that
the resulting blanket is readily flexible and, in
30 respect to handling or use, differs little from conventional blankets,
The intermediate ply 2 is faced with plies 4
and e of conventional blanket material, for example, a heavy woolen material which will pro35 vide the necessary warmth and softness. This
material alone is not particularly strong in its
resistance to tearing or destruction.
Tapes 8 of Woven type and of a comparatively
heavy nature are inserted, as indicated in the
40 drawings, between one of the outer plies and the
intermediate ply at the edges thereof and all
four plies thus resulting are stitched together by
non-raveling overseaining of a type which does
not involve chain stitches and hence cannot be
4.5 destroyed readily. 'I'he type illustrated in Fig.
2, for example, comprising three threads, can
only be destroyed with considerable diñ'iculty.
Strong heavy thread is, of course, desirable, so
that destruction by the teeth cannot be readily
In order to further reinforce the edges, lines
gies, leal/ing Square 0r rectangular areas Whieh
are preferably less than three inches on a side. 15
Desirably the areas are even smaller.
As a re
Snlt. Substantial Separation Of the Outer plies
frein the intermediate Canvas ply is imDOsSible‘
and any grip on the outer fabric can only be at
tained between the tips of the fingers, it being 20
impossible to grip a portion of the fabric within
the hand. 'As a result, it is difficult to start a
tear inwardly 0f the edges
Destruction of the blanket described substan
tially necessitates either the use of some me- 25
chanical means which, of course, should not be
available, or destruction of the stitching. All of
the stitching Sl'lOnld be 0f nOn-raVeling Charac
ter and 0f Snell heaVY, Strengr thread that break
ing, eVen by the use 0f the teetl'l, iS iInDOSSlble- 30
It will be clear that variations may be made
in the specific embodiment of the invention With
out departing from the advantageous features
Which are herein claimed.
What we claim and desire to proteet by Letters 35
